SASH-FASTENER.

Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed ltovemberl 30, 1920. Serial No. 427,435.

f( 1o all whom it' may concern.'

e it known that l, STEFAN llIoJoiii, a citizen of Poland, residing atDetroit, in the coi'lnty of llVayne and State of Michigan, have inventedcertain new and useful lmprovements in Sash-Fasteners, of which thefollowing is a specification.

rhis invention relates to certain new and useful improvements in sashfasteners` and has particular reference to a fastener supported on awindow casing and carrying tensioned bolts for engagement with `upperand lower window sashes to hold the same in closed locked positions.

A further object of the invention resides in the provision of a sashfastener supported on a window frame and carrying a pair ofindependently operable tensioned bolts adapted for reception in socketsprovided in the adjacent edges of the upper and lower window sashes tohold the sashes either in closed locked position or in various openimmovable positions, thus permitting the window to be partially openedand so retained against unauthorized movements.

lith the above general objects in View and others that will becomeapparent as the nature of the invention is better understood, the sameconsists in the novel form, combination and arrangement of partshereinafter more fully described, shown in the accom panying drawingsand claimed` In the drawings, wherein like reference characters indicatecorresponding parts throughout the several views,

Fig. 3 is a fragmentary view of the window frame showing the plun gerheads for shifting the locking bolts,

Fig. 4 is a detail sectional view showing the latch casing supported onthe window frame with the tensioned bolts carried thereby extending intosockets formed in the edges of the upper and lower window sashes,

Fig. 5 is a fragmentary side elevational view of the upper Aand lowersashes with apertured face plates secured thereto,

Fig. 7 is a perspective view of one :of the sash base plates, and

Fig. 8 is a fragmentary perspective `view of the locking bolt and aportion off-the operating mechanism therefor.

Referring more in detail to the accompanying drawings there isillustrated `a sash fastener construction associated with a windowframel supported in the wall .2, the frame 1 including a side wall 3with the adjacent edges ot upper and lower sashes 4 and 5 slidablyassociated therewith and separated by the parti-ngstrip -6 with the,forward molding 7 holding the lower sash 4 in position. As shown in Fig.5 the lower and upper sashes `4 and 5 have meeting rails Sadapted forengagement when the sashes are in their closed positions.

The edges of the sashes 4 and 5 adjacent the side wall 3 of the Windowframe are slightly out away for the counter-sunk face plates 9 securedthereto by fastening devices 10 and having vertically alined oper ings11 formed therein with overlyingflanges 12, the openings 11 in the faceplates 9 registering with socketsl in the edges of the window sashes 4and 5, into which openings sliding latch bolts are adapted to beprojected to hold the windows in operative closed locked positions orpartially open.

A latch casing 14 is disposed within the hollow window frame 1 and issecured to the side wall 3 of the frame by the fastening device 15. Apair of tensioned bolts 16 having tapered nose ends 17 projectingthrough the side of the casing 14 and through openings 18 in the framewall 3 and through the openings 11 in the face plates 9 for projectioninto the sockets 13 in the window sashes. The detail latch constructionis shown more clearly in Figs. 4,

6 and 8, a vertical pin 19 supported in the To retract the tension boltsfrom engage- 'ment with the window sashes 1 and 5, a

bell crank is associated with each vbolt 16, the bell crank beingpivotally mounted with- 'in the casing as at 24; and having thel end ofthe leg biurcated as at 26 for inclosing the pins 27 projecting from thebolt 16, the other leg 28 having an operatingl rod 29 attached theretowith a press button BO'upon the outer end whereof, the two rods 29 ofthe Operating-devices tor the two bolts 16 slidably projecting throughthe front wall of the window frame 1 with the push button positionedexterior-ly of the window frame as shown in Figs. 1 and 2 while a iaceplate 31 carried by the outer 'faceof the window frame provides asliding guide for the push buttons.` y Y From an inspection of Fig. 2 itwill be notedy that the tensioned bolts 1G are laterally disposedfforengagement with the upper and lower sashes respectively. VWhenv it isdesired to release either 4of the window sashes, the desired push button30 is operatedA to cause the rod 29 to move the bell crank and retractthe bolt 16 through the casing against the tension of the adjacentspring arm 22 to remove the tapered end 17 of the bolt from the socket13 in the window sash and the opening 11 in the sash plate'9.

By the' provision of this device, the window sashes may either be lockedin closed positions or partiall opened and so retained againstunauthorized movements.

While there is herein shown and described .the preferred embodiment ofthe present ing at their ends one side wall of the casing and said boltsto normally hold the bolts projected into sashv sockets, a bell crankpivotally mounted within the casing for each bolt and having a looseconnection therewith, and independently operable devices for operatingthe bell cranks to shift the bolts. against the tension thereon toremove the same from the sashy sockets.

In testimony whereof I aihx my signature.

STEFAN WOJCIK.
